Gaultheria Plant Named &#39;Gaulsidh12&#39;

ABSTRACT

A new cultivar of  Gautheria shallon  plant named ‘Gaulsidh12’ that is characterized by its new foliage and stem growth that is red in color, its leaves that are narrow and pointed, and its broadly spreading plant habit.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to a Canadian Plant Breeder's Rights Application No. 21-10463 filed on Apr. 15, 2021, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. This application is also co-pending with a U.S. Plant patent application filed for a plant derived from the same breeding program that is entitled Gaultheria Plant Named ‘Gaulsidh4’ (U.S. Plant patent application pending)*. *(Applicant gives the examiner the authority to replace U.S. Plant patent application pending with an Application No. or Patent No. if applicable and delete this statement.)

Botanical classification: Gaultheria shallon.

Cultivar designation: ‘Gaulsidh12’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gaultheria shallon, botanically known as Gaultheria shallon ‘Gaulsidh12’ and is hereinafter referred to by its cultivar name ‘Gaulsidh12’.

‘Gaulsidh12’ was discovered by the Inventor as a chance seedling that was growing in a container in Mission, B.C., Canada in spring of 2017. The containers had been planted with seed derived from unnamed and unpatented plants of Gaultheria shallon. The exact parents are unknown.

Asexual propagation of the new cultivar was first accomplished by tissue culture using meristemac tissue under the direction of the Inventor in Mission, B.C., Canada in spring of 2018. Asexual propagation of the new cultivar by tissue culture has shown that the unique features are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Gaulsidh12’ as a new and unique cultivar of Gaultheria.

-   -   1. ‘Gaulsidh12’ exhibits new foliage and stem growth that is red         in color.     -   2. ‘Gaulsidh12’ exhibits leaves that are narrow and pointed.     -   3. ‘Gaulsidh12’ exhibits a broadly spreading plant habit.

‘Gaulsidh12’ can be most closely compared to typical plants of Gaultheria shallon and ‘Gaulsidh4’. Both are similar to ‘Gaulsidh12’ in flower color. Typical plants of Gaultheria shallon differ from ‘Gaulsidh12’ in having leaves that are ovate to almost round in shape and in having new growth that is green in color. ‘Gaulsidh4’ differs from ‘Gaulsidh12’ in having a very compact plant habit, a smaller plant size, leaves that are smaller in size and more rounded in shape, new growth that is green in color, and in producing more flowers.
